3 Claims. 1

This invention relates generally to combined spraying and compressorunits and it relates more particularly to a portable unitary combinedsprayer and compressor unit.

Conventional spraying units of the portable type now have cumbersome,top-heavy, unbalanced structures which have made it impossible for oneman to handle a unit. Portable spraying units have not been heretoforeprovided which may be utilized to provide air under pressure.

It is, accordingly, an object of my invention to overcome the above andother defects in a portable combined spraying and compressor unit and itis more particularly an object of my invention to provide a combinedsprayer and compressor unit which is simple in construction, economicalin cost, economical in manufacture and eflicient in operation.

Another object of my invention is to provide a portable unitary combinedcompressor and sprayer unit structure which has the center of gravity aminimum height from the ground and well forward of the center.

Another object of my invention is to provide a portable combined sprayedand compressor unit which is in balance.

Another object of my invention is to provide a combined sprayer andcompressor unit in which the tank forms a part of the unitary structure.

Other objects of my invention will become evident from the followingdetailed description taken in conjunction with the accompanyingdrawings, in which:

Fig. l is a side elevational view of my novel portable combined sprayerand compressor unit;

Fig. 2 is a plan view of my novel portable combined sprayer andcompressor unit;

Fig. 3 is a front elevational view of my novel portable combined sprayerand compressor unit; and,

Fig. 4 is a side elevational view of a modified portable combinedsprayer and compressor unit in which the prime mover is a gasolinemotor.

Referring now to the drawings, Figs. 1, 2 and 3 show an uprightcylindrical tank I having a forwardly extending generally U-shaped apronor frame 2 in which is disposed a shaft 3 having mounted thereon a tiredwheel 4. The tank I has two legs 5 extending downwardly therefrom toform 3 point contact with the ground including the wheel 4. Detachablehandles 6 are attached to internally threaded bosses I extendinglaterally from the tank I and are secured thereto by threaded nuts 8. Itwill be evident that suitable handles may be secured to the tank I in ansuitable manner. A compressor unit 9 is attached to one side of theframe 2 by outwardly extending studs l I and nuts I2. An electric motorI3 is attached to the opposite side of the frame 2 by studs I4 and nutsI5. A belt I6 passes over pulley members ll and I8 on the compressorunit 9 and motor I3 respectively. A reel I9 is preferably disposed inthe frame 2 to reel an electric wire 20 for the electric motor I3.

Any other suitable means may be used other than a belt to transmit forcefrom the motor to the compressor.

It will be noted that the center of gravity of my novel unit isextremely low and well forward and when the handles 6 are lifted most ofthe weight is placed on the shaft 3 in the frame 2. The handles 6 may beremoved at any time when it is desired to ship my novel portable sprayerand compressor unit or when it is desired to store same.

Tank I .is utilized as a reservoir for compressor air to inflate tractortires, etc. and and as a container for spraying fluid when it is desiredfor spraying. This unit may be pushed between narrow rows of plants byone man. The tank may be made comparatively large because of the unitarybalanced nature of my unit and still be handled by one man.

Fig. 4 shows a balanced combined spacer and compressor unit of the sameconstruction as the unit shown in Figs. 1, 2 and 3 except that aninternal combustion motor 50 is shown attached to the frame 2 in placeof the electric motor l3 shown in Figs. 1, 2 and 3.

Various changes may be made in the specific embodiment of my presentinvention without departing from the spirit thereof and from the scopeof the appended claims.

What I claim is:

l. A portable unit of the type described comprising a verticallyextending cylindrical tank for holding compressed air or sprayingmaterial, an inclined curved frame substantially the height of said tankextending outwardly from and secured to said tank, a transverse shaftdisposed in the lower portion of said frame in substantial horizontalalignment with the bottom of said tank, wheel mounted on said shaft, acompressor unit mounted on one side of said frame and a motor mounted onthe opposite side of said frame adjacent said shaft in balanced 3. Aportable unit as set forth in claim 1 1 wherein said motor is electricand a reel is disposed centrally in said frame for reeling an electricwire for obtaining electrical energy for said motor.
